PEG

Aminooxy-PEG5-azide is a biolabeling reagent comprising an aminooxy group and an azide group. The hydrophilic PEG spacer increases solubility in aqueous media. The aminooxy group can be used in bioconjugation. by reacting with an aldehyde moiety to form an oxime bond, if a reductant is used, it will form a hydroxylamine linkage. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

N-Boc-N-bis(PEG4-azide) is a branched PEG reagent with two azide groups . The azide(N3) groups is very reactive with alkyne such as DBCO, BCN and propargyl reagnet via Click Chemistry. The protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG4-t-Boc-hydrazide is a Boc-protected PEG linker containing an azide group (N3). The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc site can be deprotected under mild acidic conditions to form a reactive hydrazide, which can then be coupled with various carbonyl groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

t-Boc-Aminooxy-PEG7-methaner contains a t-Boc-aminooxy group, which can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG9-Tos is a PEG linker containing a tosyl group. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
